Supercell B was a long track cyclic supercell that produced three long track tornadoes across southeast Missouri and southwest Illinois. The storm intensified after entering Reynolds County, Missouri and moved east across Iron, St. Francois, Madison, Ste. Genevieve, and Perry Counties in Missouri and then across the Mississippi River into Jackson County, Illinois. Of all the supercells that developed that afternoon and evening, Supercell B produced the most intense and longest track tornadoes. This included the F4 tornado that devestated the city of Crosstown in Perry County, Missouri.
